SPRING-TIRE.

Patented NOvBU. 1909.

Application tiled October 15, 1908. Serial No. 457,923.

' vation of a vehicle Wllccl and tire the same more particularly to the class of resilient or I Q U-shaped felly l1 ctrctunterenttally thereoi spring tires.

The primary object of the invention is the provision of a wheel of the resilient type in l which a non-punct'urablc tire is employed 1n 5 connection with the felly, the tire being held in position on the telly by novel means in- -uccu1nl1tutlztte the inner ends ot inwardly eluding resilient elements which support the tire so that the wheel will yield to any irregg i centrally from the inner face of an inverted ularity of the grotunl and take up any sudden shocks.

Another object of the invention is the provision of a spring tire yieldably mounted upon the felly of a wheel and which tire is nonpuncturable and formed of metal thus doing away with the use of rubber however, possessing the same or approximately the yielding qualities of a pneumatic tire.

A further object of the invention is the provision of a spring tire of novel construction which is non-puncturable and having yielding or resilient qualities to cushion sudi den shocks and which will yield to any irregu'larity of the ground when in use upon a vehicle wheel.

\Vith these and other objects in view the invention for example consists in the construction, combination and arrangement of parts as will be hereinafter more fully de- I scribed and as illustrated in the accompanying drawings which disclose the preferred form of the invention while the novelty of the said invention will be included in the appended claims.

In the drawings: Figure 1 is a side View of a vehicle wheel partly in section having a tire embodying the invention attached. Fig. 2 is a section on an enlarged scale, taken on the line 2-2 of Fig. 1. Fig. 3 is a section taken on the line 33 of Fig. 5. Fig. 4 is a plan view looking toward the tread of the tire and the same being partly broken away. Fig. 5 is an enlarged fragmentary side elebeing in section.

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

In the drawings the ntuneral 8 designates a vehicle wheel having the usual spokes projecting radially from a-hub l0 and supporting a U-shaped felly'll in cross section the same being preferably formed of wo d although it may be of any other suita l material. b'ecured at lilltlvfll within the are a plurality of radially projecting props or supports 12 upon which is mounted an annular rim 13 formed of selttl-cit'cttlu. sections the same containing at t-tpti-distant in tervals elongated slots or openings H t projecting pins 15 secured to and protruding Ushaped annular tlle section In which made of two sections the latter having their opposite parallel sides 1T disposed between and working against the inner fat-es of the parallel sides 18 of the U-shaped felly 11 of or respond by cushioning shocks imparted to the vehicle wheel due to any irregularity of the ground. The springs 19 can be'made of such strength and temper as will adapt them to support any load desired and the tire section 16 is preferably formed of metal to adapt the tire for hard surface without the danger'of a collapse incident to a pneumatic tire, however, it will have substantially the same amount of elasticity or resilient qualities of the latter owing to the interposition of the springs 19 between the folly 11 and the said tire section and thereby yieldingly support the vehicle wheel and load and adapt itself to any irregularities of a. road bed.

It is obvious owing to the interfitt' of the tire section 16 in the folly 11 ofthe vehicle wheel 8 that there is no of the said tire section 16 accidentally running from or leaving the felly of the vehicle wheel when end-thrust or lateral shifting of the vehicle wheel occurs. entering and received by the elongated 'slots or openings 14 in the annular rim 13 prevent the creeping of the tire sect-ion 16 ,on. the felly 11 however, the latter is permitted to move longitudinally'a slight distance upon the telly of the vehiclewheel so as to permit the tread portion of the tire section to easily take hold of the ground and thereby over come unnecessary injury to the same.

What is claimed is- 4 v 1. In a vehicle tire the combination with a Ushaped wheel rim, of a'plurality of props projecting at intervals from the said rim, an annulus supported by said props and containing elongated openin s arranged at equi-distant intervals throughout the same, an inverted U-shapedtire section interfitting said wheel rim, pins projecting inwardly The pins 15 from the tire section and engaging the openings, and expansionmeans interposed between the said annulus and tire section.

2. In a vehicle tire the combination with a U-shaped wheel rim, of a plurality of props projecting at intervals from the said means projecting inwardly from the tire engaging the openings in thesection and rim. v v

In testimony whereof, I aflix my signature, in presence of two witnesses.
